When to Plant Parsley in Hawaii

More than a garnish. Parsley is a biennial that produces abundantly its first year and is one of the most nutritious herbs.

The Short Answer

Parsley are planted in fall in Hawaii, 8 weeks before your first frost date. That means planting around None in Coastal Hawaii.

Your planting dates depend on which part of Hawaii you're in. Here are the frost date ranges by region:

Coastal Hawaii	11a, 11b, 12a, 12b, 13a	None	None
Upcountry/Mountain	10a, 10b, 11a	Rare	Rare

Growing Parsley in Hawaii

Parsley in Hawaii's Climate

Parsley grows from September through March in subtropical zones. More reliable than cilantro because it bolts more slowly as warmth arrives. The biennial may produce through much of Florida's mild winter without any frost protection.

Soil Considerations for Hawaii

Volcanic soils — extremely fertile but can be acidic. Excellent drainage on slopes. Varies dramatically by island and elevation.

Hawaii Climate & Growing Season

Tropical. Year-round growing season at lower elevations. Elevation creates microclimates. Plant warm-season crops anytime.

Growing season length varies across Hawaii: Coastal Hawaii (11a, 11b, 12a, 12b, 13a) has a last frost around None, while Upcountry/Mountain (10a, 10b, 11a) sees frost end around Rare. This difference matters for parsley — adjust your planting dates to match your specific region.

Growing Tips

Parsley seeds are notoriously slow to germinate — soak overnight before planting. It's a biennial: lush leaves year one, seeds year two.

Companion Planting

Plant parsley alongside these companions for better growth:

Tomatoes Asparagus Corn

The Bottom Line

Parsley can be grown successfully across Hawaii, but your exact planting dates depend on which region you're in. Coastal Hawaii gardeners should plan around a None last frost, while those in Upcountry/Mountain can typically plant later. For exact dates based on your zip code, use our free planting date finder.
